Four power-play goals propelled Ohio State to a 6-3 upset of ninth-ranked Notre Dame in a Central Collegiate Hockey Association game at Value City Arena.

The Buckeyes (11-11-5, 10-6-3-1) scored five goals in the second period to erase a 1-0 lead for the Irish (16-11-0, 12-7-0). Ryan Dzingel had two goals — both on the power play — and goaltender Brady Hjelle registered 28 saves for Ohio State.

• In front of a sold-out crowd at Oak Harbor High School, fifth-ranked Ohio State defeated No. 6 Illinois 25-9 in a Big Ten wrestling showdown.

Defending national champion Logan Stieber, a 133-pounder, returned from a December injury to pin Darryl Thomas in 2:04 to highlight the Buckeyes’ night.

Hunter Stieber (141) notched his team-leading 24th victory with a 10-2 major decision over Illini star Stephen Rodrigues, and Peter Capone (heavyweight) closed out the match with a 2-0 shutout of Chris Lopez.
